Abstract
The utility model relates to a surface deashing device for a cylindrical filtering element. The device is characterized in that: a back-blowing air flow cleaning device is arranged in a central cavity (11) of the cylindrical filtering element (1); a deashing spray nozzle (5) partially jets out a back-blowing air flow for blowing dust (7) deposited outside the cylindrical filtering element (1) away; and the deashing spray nozzle (5) of the back-blowing air flow cleaning device and the central cavity (11) are rotated relatively by a driving device to realize 360-degree cleaning. The function realized by the device breaks through a conventional cylindrical filter drum which cannot exhaust air and filter when deashing at the same time; the surface deashing device can remove ash and exhaust air normally at the same time; and thus, for a smaller filter unit, a single filter drum or a single filter bag can be adopted, which is convenient to reduce the volume of equipment and simultaneously maintains the stability of the ventilation volume and the pressure of a filter.
Description
Technical field:
The utility model relates to the method for a kind of cylindrical filter element surface deashing device.
Background technology:
Existing cylindrical filter element surface deashing device has dual mode substantially: 1. the direct deashing device of compressed air spraying cartridge interior, as shown in Figure 1, programme controlled electromagnetic membrane sheet opening of valves compressed air spraying filter cylinder inner chamber utilizes powerful impact air-flow to blow the dust or the powder of filter cylinder outside off.There is following defective in the deashing device of this structure: blowback air-flow air consumption is very big, and noise is big, and cleaning effect is poor, and blowback very big blowback air of when cleaning fail to be convened for lack of a quorum serious bucking-out system negative pressure exhausting amount and pressure cause the very great fluctuation process of air quantity and pressure.2. adopt the pneumatic deashing device of the rotation wing, as Fig. 2, shown in Figure 3, the pneumatic pallet on top is closed this filter cylinder earlier during cleaning, and compressed air 10 enters the jet pipe of the rotation wing then, and jets out from some apertures in the jet pipe outside, because the special angle of aperture, also promote to rotate wing rotation in the time of the ejection of blowback air-flow, rotate deashing end after several seconds, the cleaning air valve is closed.At this moment pneumatic pallet is opened, and filter cylinder carries out normal exhausting work.The deashing device of this structure improves a lot on cleaning effect compared with first kind of direct back flushing type deashing device, but following shortcoming is arranged also: if the filter cylinder negligible amounts of a cover filter deployment, such as disposing 3 filter cylinders altogether, if there is a filter cylinder to carry out the deashing program so, then the air quantity of exhausting system and pressure have than great fluctuation process.
Summary of the invention:
The purpose of this utility model is to provide a kind of cylindrical filter element surface deashing device, and it is applied widely, can carry out exhausting and deashing work simultaneously, and blowback air-flow air consumption is little, and cleaning effect is good.
The utility model adopts following technical scheme to realize:
A kind of cylindrical filter element surface deashing device, middle cavities the inside in cylindrical filter element is provided with blowback air-flow cleaning plant, deashing shower nozzle 5 and localized ejection go out the dust 7 that the blowback air-flow blows the deposition of cylindrical filter element 1 outside off, and the deashing shower nozzle 5 of described blowback air-flow cleaning plant by drive unit relative rotation takes place with middle cavities 11 and realizes 360 degree cleanings.
Described deashing shower nozzle only blows out the blowback air-flow in blowback air-flow cleaning plant one side or both sides.
Described blowback air-flow cleaning plant only sprays the blowback air-flow in the certain angle scope A of a side or both sides, the angle A scope is: 1 degree is to 180 degree.
Described blowback air-flow cleaning plant comprises center support main shaft, air feed axle sleeve and deashing shower nozzle, the air feed axle sleeve is rotatably connected and is sleeved on the outside of center support main shaft, center support main shaft osculant layer gas channel, at one end form the high pressure draught inlet, the deashing shower nozzle is installed in air feed axle sleeve surface, the deashing shower nozzle connects conducting element by one and is communicated with gas channel, and the gas outlet of deashing shower nozzle is near the cavity inner wall of cylindrical filter element.
The above-mentioned described sealing plate of installing around the deashing shower nozzle, sealing plate makes the gas outlet of deashing shower nozzle concentrate the cavity inner wall that blows to cylindrical filter element.
Above-mentioned described air feed axle sleeve is installed by bearing and is connected on the center support main shaft, and drive unit comprises drive rod, is connected with drive rod at an end of air feed axle sleeve, and drive rod can drive the air feed axle sleeve and rotate around the center support main shaft.
Above-mentioned described deashing shower nozzle comes pneumatic flexible by cylinder.
Above-mentioned drive rod drives by pneumatic or electrical equipment, and drive rod drives the air feed axle sleeve again and intermittently rotatablely moves around the center support main shaft.
Above-mentioned described center support main shaft is installed in by stent support on the end face of cylindrical filter element, through hole is set on the support is communicated with the middle cavities of cylindrical filter element.
A kind of cylindrical filter element surface deashing device of the utility model compared with prior art, have following advantage: 1, blowback air-flow air consumption is little, only is traditional 1/3～1/5.2, the filter cylinder cleaning effect far surpasses existing deashing device, and reason is as follows: traditional deashing all is the high-voltage pulse blowback of noncontact (non-tight) formula, though throughput is very big, can't be accurately, the concentrated area is ejected into presumptive area, so cleaning effect is limited.And the pneumatic blowback of this contact seal of the utility model, compressed air can be ejected into deashing shower nozzle institute enclosed areas like clockwork, so ash-removal effect is very good.3, little for the influence of fluctuations of the flow of exhausting system and pressure compared with traditional purge mode, be particularly useful for for the exigent pharmacy of flow and pressure like this, separate, extraction process.4) applied widely, go for single filter cylinder filter or many filter cylinders filter, this cover ingenious device of the utility model makes single filter cylinder filter deployment become possibility, can carry out reverse gas cleaning for the zone of setting cleaning in the time of single filter cylinder work, and both can carry out synchronously.Exhausting amount and pressure influence for filter are less, and design air flow and pressure oscillation scope are 1/30～1/6 as required.As obtaining little air quantity and pressure oscillation scope, can reduce the angle in each reverse gas cleaning zone.
